Tripp Lite Metered PDU, 20A Dual Circuit (PDUMV40)
This 0U vertical PDU consolidates two 20A circuits across 16 outlets per circuit, totaling 32 NEMA 5-15/20R outlets. It provides dual independent current monitoring for each circuit, helping operators balance load across racks. The dual-circuit design reduces the need for multiple PDUs, lowering space and management overhead in compact enclosures. Ideal for data centers needing straightforward, monitorable power distribution at 120V with shared 20A capacity per leg.
Key attributes include: 120V operation, dual independent circuits, 0U vertical rack-mount form factor, and color-coded outlets to simplify circuit identification. The unit ships with a 10 ft cord for versatile rack placement. Safety features center on reliable outlets and robust construction to withstand dense deployments. This model is suitable for mixed IT environments where space is at a premium and monitoring per circuit is a priority.
Usage considerations: Ensure compatible rack space and adequate cord length to reach power sources. For facilities already using single-cord PDUs, PDUMV40 can consolidate circuits while maintaining distinct monitoring, which is valuable for pinpointing overload risks and ensuring UPS efficiency.
Gelongtu 30A Metered PDU with Real-Time Readouts
The Gelongtu metered PDU provides eight outlets (8 C13), supporting 120-240V operation with a 6 ft cord and an L6-30P input. It includes an aluminum shell for durable protection in demanding environments and a built-in anti-electric shock module for safety. A prominent feature is the real-time voltage and current display, enabling operators to monitor energy usage and prevent overloads. This unit is well-suited to network equipment, servers, and switches that require reliable power distribution with visibility into consumption.
Edge cases to consider: The current-meter display supports ongoing load management, helping optimize operating costs and avoid tripped breakers. The aluminum construction adds rigidity, which is beneficial in rack-dense deployments. This PDU is best for users who want actionable load data at a glance and a compact, rugged design for 120-240V racks.
Tripp Lite PDU3MV6L2120 3-Phase Metered PDU
This 5.7 kW three-phase metered PDU supports 208/120V with a 6 ft cord and an L21-20P input plug. It includes built-in meters to report input current per phase, giving granular visibility in multi-phase rack setups. The PDU provides a total of 36 outlets (24 C13 and 12 C19 equivalents described in the spec), enabling sizable server and networking equipment deployments from a single distribution unit.
Considerations include: suitability for data centers with 3P power infrastructure, need for per-phase current reporting, and compatibility with 208V/120V equipment. The 0U vertical form factor saves rack space, while the 20A per-phase protection helps minimize overload risk across dense equipment racks.
Tripp Lite Basic PDU, 30A, 20 Outlets
This basic PDU delivers 200/208/240V single-phase power with a 30A input, distributing to 20 outlets (16 C13 and 4 C19) to support a mix of IT gear. It features a NEMA L6-30P input and a long 15-foot cord for flexible placement. The design emphasizes reliability and a switchless layout to avoid accidental downtime while providing built-in circuit protection to guard connected equipment against overloads. This is a straightforward option for networks, security devices, and A/V applications needing reliable, no-frills distribution at higher voltages.
Usage considerations: It’s a solid fit where a simple, rugged, and cost-effective PDU is needed without complex metering. For environments requiring precise load metrics, pairing with external power monitoring tools may be beneficial. This unit complements existing UPS or generator connections in mixed-volt racks.
Tripp Lite Metered PDU, 30A, 48 Outlets (PDUMV30HV2)
This 0U vertical PDU distributes up to 30A of 208/240V single-phase power with up to 48 outlets split into two banks (24 outlets per bank, including 4 C19 and 20 C13 per bank). It features dual load banks and dedicated 20A circuit breakers to safeguard output against overloads. This model is well-suited for high-density server rooms and data centers that require substantial outlet counts with metered power distribution to manage energy use and avoid outages in critical equipment clusters.
Important considerations include: ensuring 208/240V equipment compatibility, the need for two load banks to segregate critical loads, and ensuring the rack has space for a 0U — maximizing floor space usage. The combination of high outlet count and metering makes this an attractive option for scalable deployments with robust monitoring requirements.
Buying Guide: Key Purchase Considerations And Comparisons
When selecting a PDU for 208V input and 120V output, consider the following aspects to ensure the right fit for your rack and workload profile:
- Voltage and phase compatibility: Confirm your facility voltage (208V single-phase, 120/208V three-phase, or 208/240V three-phase) and pick a PDU that matches or safely supports your equipment.
- Metering capability: Decide if you need real-time per-circuit or per-phase current readings. Meted PDUs help with load balancing, capacity planning, and preventive maintenance.
- Outlet configuration: Count required outlets and outlet types (C13, C19, etc.). More outlets support densely populated racks; consider future growth.
- Form factor and mounting: 0U PDUs save rack space but may require careful planning for cable management; 1U PDUs are easier to access for maintenance.
- Circuit protection: Built-in breakers per bank or per circuit reduces overload risk. For critical gear, dual circuits with independent protection can be valuable.
- Safety features: Anti-electric shock modules, durable enclosures (aluminum or steel), and robust cord management improve safety and longevity in busy data centers.
- Cord length and placement: Ensure cords reach power sources without creating congestion or tripping hazards. Longer cords provide flexibility but can complicate cable routing.
- Compliance and reliability: Look for models with reputable brands, compatibility with UPS and generator inputs, and certifications (e.g., TAA compliance if required).
- Budget vs. scalability: Balanced approaches—start with metered PDUs for visibility and add extra PDUs or remote monitoring as your rack density grows.
- Management and monitoring integration: If you have a DCIM or monitoring solution, verify compatibility for centralized control and alerting.
In summary, the five selected PDUs provide a range of capabilities—from simple, rugged 208/240V distribution to advanced metered, multi-bank configurations suitable for high-density racks. For users prioritizing load visibility, metering, and phase-aware distribution, models like the PDUMV40 and PDUMV30HV2 offer robust monitoring along with scalable outlet counts. For environments where space is at a premium and three-phase power is common, the 3MV2 series PDUs deliver per-phase current reporting and strong protection.
